The syntax of functions in C++ inspired the function prototype syntax found in ANSI C. A C++ function lists the types of the function's
parameters inside the header parentheses. Explicitly listing the type and number of arguments makes strong type checking and
assignment-compatible conversions possible.
This list of a function's arguments in the header parentheses is called the function's signature.
